Updating flag count via ajax

I'm not sure what you mean by this. The only thing I can assume is that you are displaying a count in your flag link's text, in which case it would be more practical to use the token for the count in your flag's settings.

If I'm assuming wrong, can you please elaborate where you are trying to use $flag->get_count()?

You would have to write your own custom jQuery to handle that.

I would suggest using the token in your flag's text and then styling it to put a background image. But that's without seeing your design.

I don't think you'd be able to style them separately as they'd be the same element. However, I think that the return text can take in a token as well and maybe that could be where you put your count, that would make it a separate element and give the ability to style it differently then the text.

Miraploy, you don't need to know anything about Ajax.

1. As theme/README.txt explains:

1.a Copy flag.tpl.php into flag-YOURFLAGFNAME.tpl.php.

1.b Move it into your theme folder.

1.c Clear Drupal's cache.

2. Put $flag->get_count($content_id) in that file. Whatever in that tpl file is fetched anew with every mouse click.

Can also be done through tokens. see http://drupal.org/node/319491.

Just need to track this thread...

...it works on comments too :-)

In D7 version, just copy flag.tpl.php and paste it in YOURTHEME/tamplates folder. No need to change name.

Thank you for this #6.
Just wanted to precise that adding the flag machine name to flag--flag_machine_name.tpl.php instead of just flag.tpl.php is not related to D6 or D7, it just allows to only target one flag or everyone of them... Beware that just one hyphen '-' did not work for me but two '--' did in flag--like.tpl.php
Also $content_id does not work anymore, $entity_id does though.
Here's my code preparing the count:

<?php
  $flag_jaime = flag_get_flag('jaime');
  $jaime_count = $flag_jaime->get_count($entity_id);
  if ($jaime_count != 0) {
    $jaime_count = '<span class="jaime_count">' . $jaime_count . '</span>';
  }
  else {
    $jaime_count = '';
  }
?>

and then actually displaying the flag count:

<?php
<?php if ($link_href): ?>
    <a href="<?php print $link_href; ?>" title="<?php print $link_title; ?>" class="<?php print $flag_classes ?>" rel="nofollow"><?php print $link_text . $jaime_count; ?></a><span class="flag-throbber">&nbsp;</span>
  <?php else: ?>
    <span class="<?php print $flag_classes ?>"><?php print $link_text . $jaime_count; ?></span>
  <?php endif; ?>
?>

Fantastic! Thanks. I can't imagine why this isn't built into the module as a standard display option.
